The capture of Alisson continues a big-spending off-season from the beaten Champions League finalists.

Naby Keita, Fabinho and Xherdan Shaqiri are the other players to have already joined in what appears a concerted move to transform the perennial Premier League underperformers into genuine title contenders.

Klopp, however, warned it may take time for Alisson to adjust to his new surroundings, despite being "the full package".

"The league is different, the refs are different, the goalkeeper life is different in the Premier League," the German said.

"But that's not important now because again, we got him here because of his existing strengths, which is in all goalkeeper departments the highest level.

"But of course he still has to adapt and age-wise he can improve, the best years are coming in the goalkeeper life, so it's all good."
